摘　　要：目的分析中国汉族人群骨性膝关节炎患者膝关节冠状位对线(CPAK)分型的分布。方法随机选取200例汉族骨性膝关节炎患者的下肢全长片。测量股骨远端外侧角(LDFA)、胫骨近端内侧角(MPTA),计算算术髋膝踝角(aHKA)、关节线倾斜度(JLO)等参数,确定CPAK分型。结果膝关节CPAK分型依次为Ⅰ型(36.5%)、Ⅳ型(29.0%)、Ⅱ型(12.7%)、Ⅲ型(9.5%)、Ⅴ型(6.4%)、Ⅶ型(3.5%)、Ⅵ型(2.0%)、Ⅷ型(0.4%),无Ⅸ型。结论在中国汉族人群的CPAK分型中,结构性内翻对线伴顶点远端JLO占比最高。Objective To analyze the distribution of the types of coronal plane alignment of the knee(CPAK)in patients with osteoarthritis of the knee in Chinese Han population.Methods Full-length films of the lower limbs were collected from 200 Han patients with osteoarthritis of the knee.The lateral distal femoral angle(LDFA)and medial proximal tibial angle(MPTA)were measured,and parameters such as arithmetic hip-knee-ankle angle(aHKA)and joint line obliguity(JLO)were calculated.The CPAK types were determined.Results The majority of CPAK types of the knee were typeⅠ(36.5%),followed by typeⅣ(29.0%),typeⅡ(12.7%),typeⅢ(9.5%),typeⅤ(6.4%),typeⅦ(3.5%),typeⅥ(2.0%),and typeⅧ(0.4%),without typeⅨ.Conclusions Among the CPAK types in Chinese Han population,structural inversion alignment with proximal JLO at the apex accounted for the highest percentage.
